There are cosmetic dirt/stain marks.  I have tried to clean with basic wash cloth and water but was unsuccesful in getting rid of any of the stains. Maybe you have a more advanced cleaning then I do.

From an audio standpoint it sounds great.  I really like the handle in between the speakers for carrying.Item has been tested and works.  Plays cds including burned cds and plays the radio.  Has Sony "megabass" button.
